  Referring to FIGS. 1 to 5, an ultrasonic generator according to an embodiment of the present invention is a medical device that performs various treatments using high intensity focused ultrasound (HIFU). obtain.

  In the above-described embodiment, the ultrasonic wave generation apparatus can perform two or more different treatments. For example, the ultrasound generator can perform non-invasive face lifting, skin tightening procedures, and non-invasive subcutaneous fat layer reduction or removal procedures.

  The high-intensity focused ultrasound (hereinafter referred to as “HIFU”) is for focusing ultrasound on one focal point to form a thermal lesion (12). Such a thermal lesion 12 may be a thermal focus at a high temperature of approximately 60 ° C. or higher.

  That is, the ultrasonic generator 10 forms the thermal lesion 12 on the dermis layer, fascia layer, or SMAS layer located approximately 1.5 mm to 4.5 mm from the skin surface, and performs face lifting (face lifting) Fat reduction is performed by performing a lifting or skin tightening operation or by forming the thermal lesion 12 on the subcutaneous fat layer located approximately 6.0 mm to 15.0 mm from the skin surface. Or removal treatment can be performed.

  On the other hand, the ultrasonic generator 10 according to the embodiment may include the equipment main body 100, the handpiece assembly 200, the cartridge set 300, and the like.

  The equipment main body 100 provides treatment-related information to a practitioner (not shown) and allows the practitioner to operate or operate the ultrasonic generator 10. For example, the equipment main body 100 is provided with a display 110 for displaying the treatment-related information of the practitioner and a controller 120 for the practitioner to operate or control the ultrasonic generator 10. Here, a touch screen or the like can be used as the controller 120.

  The handpiece assembly 200 includes a surgical handpiece 210 and a connecting cable 220. The treatment handpiece 210 is for irradiating a person to be treated with HIFU, and may be in a hand-held form in order to improve user's operation convenience. For example, the treatment handpiece 210 can be provided with a handle portion 212 so that a practitioner can hold the treatment handpiece 210. A switch 212a for the practitioner to control the ultrasonic irradiation operation may be provided at the upper end of the handle portion 212. The connection cable 220 is for electrically and physically connecting the treatment handpiece 210 and the equipment main body 100. One end of the connection cable 220 is connected to the treatment handpiece 210, and the other end is connected to the equipment main body 100 in a detachable connection type.

  In the embodiment, the cartridge set 300 is a set composed of a plurality of cartridges. For example, the cartridge set 300 may include first to third cartridges 310, 310-1, and 310-2 having different types of treatment or treatment conditions. The first to third cartridges 310, 310-1, and 310-2 can be configured to be detachable from the surgical handpiece 210, respectively. For example, the functions of the first cartridge 310 and the second cartridge 310-1 are divided according to the obesity state of the obese patient or the treatment site. Specifically, the conditions such as the irradiation intensity and depth of the HIFU, Different conditions can be used. In addition, the third cartridge 310-2 can be set with the irradiation intensity and depth conditions of the HIFU for performing face lifting or skin tightening treatment. Furthermore, a cartridge for removing tumor or cancer tissue can be applied.

  More specifically, the first to third cartridges 310, 310-1 and 310-2 have a treatment section of approximately 40.0 mm to 100.0 mm, and the transducer 314 provided therein has front and rear Each is configured to move in the direction. At this time, the transducer 314 can irradiate the HIFU while moving in the above range. On the other hand, when the range of movement of the transducer 314 back and forth is less than 40.0 mm, the treatment time may be very long because the treatment region is small. The transducer 314 is set to irradiate HIFU at a certain depth, and the subcutaneous fat layer is bent and spreads in both directions with reference to the human navel, so the transducer 314 moves back and forth. If the range exceeds 100.0 mm, the initial HIFU irradiation depth for the subcutaneous fat layer may be different from the final HIFU irradiation depth. As a result, there is a risk that the risk of HIFU being irradiated to a region outside the subcutaneous fat layer becomes very high. Therefore, the transducer 314 is set so as to be movable back and forth within a range of approximately 40.0 mm to 100.0 mm, more preferably within a range of 60.0 mm to 80.0 mm. It is advantageous for shortening the treatment time while ensuring safety.

  As described above, the ultrasonic generator 10 according to the embodiment includes the cartridge set 300 including the first to third cartridges 310, 310-1 and 310-2 having different types of treatment or treatment conditions. Thereafter, by selecting a cartridge suitable for the type of treatment and treatment conditions and mounting the cartridge on the treatment handpiece 210, a custom-type treatment can be performed for each patient.

  On the other hand, in the ultrasonic generator 10 according to the above embodiment, the rotational force outside the first to third cartridges 310, 310-1, 310-2 is transmitted to the inside of the cartridge, and this rotational force is used. The transducer 314 can be moved in a linear direction.

  In the above-described embodiment, the first cartridge 310 includes a rotational force application unit 350, a conversion unit, and a transducer 314 provided in an area surrounded by the housing 312.

  The rotational force application unit 350 has a function of receiving application of rotational force provided from the outside of the housing 312. As an example, the rotational force is transmitted to the rotational force applying unit 350 from the outer rotating unit 233 that rotates outside the housing 312. Here, the rotational force application unit 350 and the outer rotation unit 233 are arranged so as not to contact each other directly and to face each other with the housing 312 interposed therebetween. And the rotational force application part 350 and the outer side rotation part 233 are connected with the magnetic force. At this time, the rotational force application unit 350 and the outer rotation unit 233 may be formed of a magnetic material or may include a magnetic material. Further, the magnetic coupling force between the rotational force applying part 350 and the outer rotating part 233 is formed by configuring a region of the housing 312 between the rotational force applying part 350 and the outer rotating part 233 with a nonmagnetic substance. Can be minimized. Of course, the entire housing 312 may be made of a non-magnetic material, but the housing 312 may be made of a magnetic material as long as it is not in the region between the rotational force applying part 350 and the outer rotating part 233.

  In the above-described embodiment, the rotational force application unit 350 and the outer rotation unit 233 are configured in a substantially disk shape. Accordingly, it is possible to occupy a minimum space while maximizing the magnetic coupling force between the rotational force application unit 350 and the outer rotational unit 233, and it is possible to minimize the frictional force.

  In addition, the housing 312 has a recess, and the rotational force applying unit 350 and the outer rotating unit 233 are stabilized by inserting a part of the rotating force applying unit 350 and the outer rotating unit 233 into the recess. Thus, the rotational force applying unit 350 and the outer rotating unit 233 can be smoothly rotated while being supported.

  Further, a member such as a bearing is provided between the rotational force application unit 350 and the housing 312 and between the outer rotational unit 233 and the housing 312 so that a smooth rotational motion can be achieved by reducing the frictional force. May be provided.

  In the above embodiment, the outer rotating part 233 is connected to the rotating shaft 232 of the motor 231. The motor 231, the rotating shaft 232, and the outer rotating portion 233 are provided on the treatment handpiece.

  Here, referring to FIG. 2, the first cartridge 310 is coupled to the treatment handpiece 210. At this time, the outer rotating portion 233 is located at a portion where the first cartridge 310 and the treatment handpiece 210 are in contact with each other. To position. Then, as shown in FIG. 2, at least a part of the outer rotating portion 233 protrudes outside the treatment handpiece 210 and is inserted into the concave portion of the housing 312, whereby the outer rotating portion 233 and the rotational force applying portion 350 are The magnetic coupling force between is maximized. Although not shown, the surface of the housing 312 with which the rotational force application unit 350 contacts protrudes in the direction of the outer rotational unit 233, and the projecting portion of the rotational force application unit 350 is inserted into the treatment handpiece 210. Configuration is also possible.

  On the other hand, the conversion unit is provided between the rotational force application unit 350 and the transducer 314, and has a function of converting the rotational motion of the rotational force application unit 350 into a linear motion and providing it to the transducer 314. Thereby, the transducer 314 can move in the linear direction inside the first cartridge 310.

  In the above embodiment, the conversion unit may include a main drive 340 that performs a rotational motion and a follower 330 that performs a linear motion. For example, the groove 341H is formed in a spiral shape on the surface of the cylindrical cam 341 configured in a columnar shape, and the main drive node 340 can be configured by rotating the cylindrical cam 341, and is inserted into the groove 341H of the cylindrical cam 341. The follower 330 can be configured by causing the transfer member 331 coupled to the protruding portion 332 to move in a linear direction along the guide portion 333. Although not shown, it is also possible to adopt a configuration in which a protrusion is formed in a spiral shape on the surface of the cylindrical cam 341 and a groove 341H to be inserted into the protrusion 332 is formed in the transfer member 331.

  Further, by fixing the transducer 314 to the transfer member 331, the transducer 314 can move in the linear direction together with the transfer member 331 as the transfer member 331 moves in the linear direction.

  In the above embodiment, one end of the cylindrical cam 341 is connected to the rotational force applying unit 350. On the other hand, the other end of the cylindrical cam 341 is rotatably coupled to the housing 312. That is, as shown in FIG. 4, the housing 312 is provided with a concave groove, the cylindrical cam 341 is provided with a shaft protrusion 342, and the shaft protrusion 342 is inserted into the groove so that the cylindrical cam 341 is provided. Is pivotally coupled to the housing 312. Thereby, when the rotational force application unit 350 receives the rotational force from the outer rotational unit 233 and rotates, the cylindrical cam 341 also rotates.

  In the above-described embodiment, the groove portion 341H provided on the surface of the cylindrical cam 341 starts from one side of the cylindrical cam 341 and returns to one end of the cylindrical cam 341 via the other side of the cylindrical cam 341. Can be configured to form a circle. As a result, while the cylindrical cam 341 rotates 360 degrees, the transfer member 331 and the transducer 314 move along the guide portion 333 and return to the original position, more specifically, linear reciprocation. Can be executed. At this time, the rotational speed of the cylindrical cam 341 can be adjusted in consideration of the linear reciprocating speed of the transducer 314. The rotational speed of the motor 231 described above can be adjusted, or the rotating shaft 232 and the outer rotating part of the motor 231 can be adjusted. The rotational speed can be adjusted by arranging a gear (not shown) or the like between 233 and the like.

  In an embodiment different from the above-described embodiment, the groove portion 341H provided on the surface of the cylindrical cam 341 may be formed so as to advance only in one direction. In this case, the transfer member 331 and the transducer 314 can move forward or backward depending on the rotation direction of the cylindrical cam 341. For example, when the cylindrical cam 341 rotates in the clockwise direction, the transfer member 331 and the transducer 314 move forward, and when the cylindrical cam 341 rotates in the counterclockwise direction, the transfer member 331 and the transducer 314 can move backward. On the other hand, in the ultrasonic generator 10 according to the above embodiment, the rotational force application unit 350 and the outer rotational unit 233 are coupled by a magnetic force. There is a possibility that the magnetic coupling with the outer rotating part 233 is momentarily broken. Therefore, the diameter and rotational speed of the cylindrical cam 341 can be determined in consideration of the linear reciprocating speed of the transducer 314 and the magnetic coupling force between the rotational force applying part 350 and the outer rotational part 233. .

  In the above-described embodiment, a transmissive member may be provided in the first cartridge 310 in the direction in which the ultrasonic wave generated by the transducer 314 passes. This transmitting member can be constituted by a window made of a material that can smoothly transmit ultrasonic waves.

  The empty space inside the first cartridge 310 is filled with fluid (L). This fluid (L) plays a role as a kind of medium for smoothly transmitting the ultrasonic wave generated by the transducer 314 to the outside of the first cartridge 310. The fluid (L) can also have a function of cooling the transducer 314. For example, a heat generation phenomenon can be induced in the process of generating ultrasonic waves by the transducer 314, but such heat generation phenomenon can be mitigated by the fluid (L) described above.

  Therefore, at least a region from the transmission member of the first cartridge 310 to the transducer 314 needs to be filled with the fluid (L) described above. In addition, while the first cartridge 310 is coupled to the treatment handpiece 210 and the first cartridge 310 is in contact with the body of the treatment subject and the treatment is performed, the transmission member of the first cartridge 310 is always vertical. It may not be pointing down. Therefore, it is preferable to determine the filling amount of the fluid (L) described above in consideration of the inclination range in the direction in which the transducer 314 is directed during the treatment. Of course, it is also possible to fill the empty space inside the first cartridge 310 with the above-described fluid (L).

  On the other hand, when the fluid (L) is filled in the first cartridge 310 in this way, the flow-off cycle of the fluid (L) may change depending on the degree of sealing inside the first cartridge 310. For example, when the sealing degree is low, the fluid (L) inside the first cartridge 310 decreases as time elapses. In this case, there may occur a problem that the fluid (L) must be replenished or the first cartridge 310 itself must be replaced. However, in the ultrasonic generator 10 according to the above-described embodiment, the rotational force applying unit 350 provided inside the cartridge receives the rotational force provided from the outer rotating unit 233 provided outside the cartridge, and is applied thereto. The transducer 314 can be linearly moved or reciprocated linearly by converting the rotational force through the converter. Further, since the rotational force application unit 350 and the outer rotation unit 233 are coupled by magnetic force, the sealing degree of the first cartridge 310 can be improved. That is, the ultrasonic generator 10 according to the above-described embodiment uses a driving force outside the first cartridge 310 to convert the transducer without using a component penetrating the outer wall of the first cartridge 310 or the housing 312. 314 can be linearly moved or reciprocated linearly.

  Therefore, the ultrasonic generator 10 according to the above embodiment can improve the sealing degree of the cartridge as compared with the case where a component penetrating the outer wall of the cartridge or the housing 312 is required. By extending the replacement period, the convenience of use and maintenance of the ultrasonic generator 10 can be improved. Further, the ultrasonic generator 10 according to the above embodiment does not need to be provided with a separate means for improving the sealing degree of the cartridge, and is simplified through the above-described rotational force applying unit 350 and the conversion unit. In addition, since the transducer 314 can be linearly moved or reciprocated linearly with the above structure, it is advantageous in reducing the size of the cartridge and the treatment handpiece and reducing the manufacturing cost.

  Although the first cartridge 310 has been described above as a reference, the second cartridge 310-1 and the third cartridge 310-2 can be configured in a similar manner to the first cartridge 310, and redundant description is omitted.

  Moreover, S3 and S4 displayed in FIG. 3 mean a third sensor and a fourth sensor, respectively, and embodiments including these sensors will be described later with reference to FIGS.

  Hereinafter, another embodiment of the present invention will be described with reference to FIGS. Here, the description which overlaps with the content described above is omitted.

Here, the input unit 430 can be configured by a physical button or a touch screen method. In FIG. 6 and the like, the display unit 420 and the control unit 440 are illustrated separately, but the display unit 420 and the input unit 430 are input. The part 430 may be integrally formed by a touch screen method.

  The display unit 420 and the input unit 430 are connected to the control unit 440 illustrated in FIG. 9, and the operator's command applied to the input unit 430 is transmitted to the control unit 440 so that the ultrasonic generator 20 Operated or controlled.

  In the other embodiment, a power supply unit 460 is provided inside the treatment handpiece 410. This eliminates the need to connect a separate cable or the like for supplying external power to the surgical handpiece 410, thereby improving convenience during various surgical procedures using the surgical handpiece 410. Here, the power supply unit 460 can be configured by a secondary battery such as a lithium ion battery. Further, when the surgical handpiece 410 is installed on the installation table 600, the power supply unit 460 is configured to be charged. You can also On the other hand, the vent 411 may have a function of reducing the overheating phenomenon of the treatment handpiece 410 and the cartridge by circulating air inside the treatment handpiece 410.

  The cartridge set 500 means a set composed of a plurality of cartridges. As an example, the cartridge set 500 may include first to third cartridges 510, 510-1, 510-2 having the same or similar treatment type or treatment conditions. The first to third cartridges 510, 510-1 and 510-2 can be configured to be detachable from the treatment handpiece 410, respectively.

  As described above, the ultrasonic generator 20 according to the other embodiment includes the cartridge set 500 including the cartridges 510, 510-1, and 510-2 having the same treatment type or treatment condition, and then has a lifetime. By replacing the completed cartridge with a new cartridge and using it on the surgical handpiece 410, when the life of the transducer 514 is over, the entire ultrasonic generator 20 is not purchased, but the cartridge is replaced. It can be used continuously.

  In addition, the cartridge set 500 may include first to third cartridges 510, 510-1, 510-2 having different types of treatment or treatment conditions. The first to third cartridges 510, 510-1 and 510-2 can be configured to be detachable from the treatment handpiece 410, respectively. For example, the functions of the first cartridge 510, the second cartridge 510-1, and the third cartridge 510-2 are divided according to the skin or obesity state of the person to be treated, or the treatment site. The conditions such as the irradiation intensity and depth of the HIFU can be different from each other.

  More specifically, the first to third cartridges 510, 510-1, 510-2 have a treatment section of approximately 40.0 mm to 100.0 mm, and the transducer 514 provided inside thereof is Each is configured to move in the direction. At this time, the transducer 514 can irradiate the HIFU while moving in the above range. On the other hand, when the range of movement of the transducer 514 is less than 40.0 mm, the treatment time may be very long because the treatment region is small. Further, the transducer 514 is set to irradiate HIFU at a certain depth, and the subcutaneous fat layer is bent and expanded in both directions with respect to the human navel, so that the transducer 514 moves back and forth. If the range exceeds 100.0 mm, the initial HIFU irradiation depth for the subcutaneous fat layer may be different from the final HIFU irradiation depth. As a result, there is a risk that the risk of HIFU being irradiated to a region outside the subcutaneous fat layer becomes very high. Therefore, it is possible to set the transducer 514 so that it can move back and forth within a range of approximately 40.0 mm to 100.0 mm, more preferably within a range of 60.0 mm to 80.0 mm. It is advantageous to shorten the treatment time while ensuring the performance.

  In the ultrasonic generator 20 according to the other embodiment, the rotational force outside the first to third cartridges 510, 510-1, and 510-2 is transmitted to the inside of the cartridge, similarly to the one embodiment. Using this rotational force, the transducer 514 can be moved in a linear direction.

  In the other embodiment, the first cartridge 510 includes a rotational force application unit 550, a conversion unit, and a transducer 514 provided in an area surrounded by the housing 512.

  The rotational force application unit 550 has a function of receiving application of rotational force provided from the outside of the housing 512. As an example, the rotational force is transmitted to the rotational force applying unit 550 from the outer rotating unit 453 that rotates and moves outside the housing 512. Here, the rotational force application unit 550 and the outer rotation unit 453 are disposed so as not to directly contact each other and to face each other with the housing 512 interposed therebetween. And the rotational force application part 550 and the outer side rotation part 453 are connected with the magnetic force. At this time, the rotational force applying unit 550 and the outer rotating unit 453 may be made of a magnetic material or may include a magnetic material. In addition, by forming a region of the housing 512 between the rotational force applying unit 550 and the outer rotating unit 453 from a nonmagnetic material, the magnetic coupling between the rotational force applying unit 550 and the outer rotating unit 453 is achieved. Force reduction can be minimized. Of course, the entire housing 512 may be made of a non-magnetic material, but the housing 512 may be made of a magnetic material as long as it is not in the region between the rotational force applying part 550 and the outer rotating part 453.

  In the other embodiment, the rotational force applying unit 550 and the outer rotating unit 453 are configured in a substantially disc shape. Accordingly, it is possible to occupy a minimum space while maximizing the magnetic coupling force between the rotational force applying unit 550 and the outer rotational unit 453, and it is possible to minimize the frictional force.

  In addition, the housing 512 has a recess, and the rotational force application unit 550 and the outer rotation unit 453 are stably inserted by inserting a part of the rotation force application unit 550 and the outer rotation unit 453 into the recess. While being supported, the rotational force applying unit 550 and the outer rotating unit 433 can be smoothly rotated.

  In addition, a member such as a bearing is provided between the rotational force application unit 550 and the housing 512 and between the outer rotational unit 453 and the housing 512 so that a smooth rotational motion can be achieved by reducing the frictional force. Can also be provided.

  In the other embodiment, the outer rotating part 453 is connected to the motor shaft 452 of the motor 450. The motor 450, the motor shaft 452, and the outer rotating portion 453 are provided on the treatment handpiece 410.

  Here, referring to FIG. 7, the first cartridge 510 is coupled to the treatment handpiece 410, and at this time, the outer rotating portion 453 is disposed at a portion where the first cartridge 510 and the treatment handpiece 410 are in contact with each other. Is located. Then, as shown in FIG. 9, at least a part of the outer rotating portion 453 protrudes outside the treatment handpiece 410 and is inserted into the concave portion of the housing 512, so that the outer rotating portion 453 and the rotational force applying portion 550 are The magnetic coupling force between is maximized. Although not shown in the drawings, the surface of the housing 512 with which the rotational force application unit 550 comes into contact protrudes in the direction of the outer rotational unit 453, and the protruding part of the rotational force application unit 550 is inserted into the treatment handpiece 410. Is possible.

  On the other hand, the conversion unit is provided between the rotational force application unit 550 and the transducer 514, and has a function of converting the rotational motion of the rotational force application unit 550 into a linear motion and providing it to the transducer 514. Thereby, the transducer 514 can move in the linear direction inside the first cartridge 510.

  In the other embodiment, the conversion unit may include a main node that performs a rotational movement and a driven node that performs a linear movement. For example, the groove 541H is formed in a spiral shape on the surface of the cylindrical cam 541 configured in a columnar shape, and the main drive node can be configured to rotate, and the protrusion 532 inserted into the groove 541H of the cylindrical cam 541. The follower node can be configured such that the transfer member 531 having the position moves in a linear direction along the guide portion 533. Although not shown in the drawings, the main driving node and the driven node can be coupled by forming a protruding portion in a spiral shape on the surface of the cylindrical cam 541 and providing the transfer member 531 with a concave groove into which the protruding portion is inserted.

  Further, by fixing the transducer 514 to the transfer member 531, the transducer 514 can move in the linear direction together with the transfer member 531 as the transfer member 531 moves in the linear direction. Here, the transducer 514 and the transfer member 531 may be collectively referred to as an ultrasonic wave generation unit.

  In the other embodiment, one end of the cylindrical cam 541 is connected to the rotational force applying unit 550. On the other hand, the other end of the cylindrical cam 541 is rotatably coupled to the housing 512. That is, as shown in FIG. 9, the housing 512 is provided with a concave groove, the cylindrical cam 541 is provided with a shaft protrusion 542, and the shaft protrusion 542 is inserted into the groove so that the cylindrical cam 541 is provided. Is rotatably coupled to the housing 512. Accordingly, when the rotational force application unit 550 receives the rotational force from the outer rotational unit 453 and rotates, the cylindrical cam 541 also rotates. FIG. 9 and the like illustrate a configuration in which the cylindrical cam 541 and the rotational force applying unit 550 are configured by respective units and coupled. However, the cylindrical cam 541 and the rotational force application unit 550 may be integrally formed. However, the rotational force application unit 550 must be made of a magnetic material or include a magnetic material for magnetic connection with the outer rotation unit 453, while the cylindrical cam 541 needs to be made of a magnetic material. Therefore, it is advantageous to combine the cylindrical cam 541 and the rotational force application unit 550 after they are made of different materials from the viewpoint of reducing manufacturing costs and improving manufacturing efficiency. Accordingly, at least one locking protrusion is provided at the coupling portion between the cylindrical cam 541 and the rotational force application unit 550 so that the rotational motion of the rotational force application unit 550 is effectively transmitted to the cylindrical cam 541. Can do.

  In the other embodiment described above, the groove 541H provided on the surface of the cylindrical cam 541 starts from one side of the cylindrical cam 541 and returns to one end of the cylindrical cam 541 via the other side of the cylindrical cam 541. Can be configured to form a circle. As a result, while the cylindrical cam 541 rotates 360 degrees, the transfer member 531 and the transducer 514 advance along the guide portion 533 and return to the original position, more specifically, linear reciprocation. Can be executed. At this time, the rotational speed of the cylindrical cam 541 can be adjusted in consideration of the linear reciprocating speed of the transducer 514. The rotational speed of the motor 450 described above can be adjusted, or the rotational axis of the motor 450 and the outer rotating part 453 can be adjusted. The rotational speed can be adjusted by arranging a gear (not shown) or the like between them.

  In an embodiment different from the other embodiments described above, the groove 541H provided on the surface of the cylindrical cam 541 may be formed so as to advance only in one direction. In this case, the transfer member 531 and the transducer 514 can move forward or backward depending on the rotation direction of the cylindrical cam 541. For example, when the cylindrical cam 541 rotates in the clockwise direction, the transfer member 531 and the transducer 514 advance, and when the cylindrical cam 541 rotates in the counterclockwise direction, the transfer member 531 and the transducer 514 can move backward. On the other hand, in the ultrasonic generator 20 according to the other embodiment described above, the rotational force application unit 550 and the outer rotational unit 453 are coupled by magnetic force. There is a possibility that the magnetic coupling between the outer rotating part 453 and the outer rotating part 453 may be momentarily broken. Therefore, the diameter and rotational speed of the cylindrical cam 541 can be determined in consideration of the linear reciprocating speed of the transducer 514 and the magnetic coupling force between the rotational force applying unit 550 and the outer rotating unit 453. .

  Meanwhile, the ultrasonic generator 20 according to the other embodiment may include a position sensing unit and a control unit. Here, the position sensing means senses the position of the ultrasonic wave generation unit, and the control means can have a function of controlling the ultrasonic wave generation operation using the result sensed by the position sensing means. For example, the control unit performs control so that the ultrasonic wave is not generated when the ultrasonic wave generator is not moved by a predetermined distance after the ultrasonic wave is generated in a state where the ultrasonic wave generator is in any position. I can.

  If the ultrasound generated by the ultrasound generator is HIFU, a thermal lesion will be formed at a specific site, but if the thermal lesion persists excessively at the same location, it will be different from the intention. There is a risk of damage. That is, after a thermal lesion is formed at a specific site, if a thermal lesion is formed again without moving the ultrasonic generator for a certain distance, a specific point of the human body organization is excessively stimulated and pain or Bleeding, injury, etc. may occur. However, according to the other embodiment, immediately after the ultrasonic wave is generated by the ultrasonic wave generating unit, when the ultrasonic wave generating unit does not move more than a predetermined distance, the control can be performed so that no ultrasonic wave is generated. Therefore, the risk described above can be significantly reduced. Here, the presence or absence of movement of the ultrasonic wave generation unit can be detected by the position sensing unit described above, and the control unit controls the presence or absence of ultrasonic wave generation of the ultrasonic wave generation unit based on the detection result, The risk that the ultrasonic wave is excessively applied to a specific position can be reduced. On the other hand, the above-mentioned “predetermined distance” can be appropriately determined according to the intensity of the ultrasonic wave generated by the ultrasonic wave generation unit, the size of the thermal lesion, the type of tissue to be irradiated with ultrasonic waves, and the like.

  The ultrasonic generator is a concept including the transducer 514 and the transfer member 531 described above, and the transducer 514 linearly moves in a state of being coupled to the transfer member 531. By sensing the position of the transducer 514 or the transfer member 531, the functions described above can be performed. Further, since the transfer member 531 moves linearly by the rotation of the cylindrical cam 541 described above, the position of the ultrasonic wave generation unit can be detected by sensing the degree of rotation of the cylindrical cam 541.

  In the other embodiment, the position sensing unit may include a magnet part and a sensor. The sensor can be composed of a Hall sensor. The signal output by the sensor changes depending on the positional relationship between the magnet unit and the hall sensor, and the relative positional relationship between the magnet unit and the sensor can be detected using the degree of this change. .

  More specifically, the ultrasonic generator 20 according to the other embodiment includes a first magnet portion 541m provided in the cylindrical cam 541 and a first sensor disposed to face the first magnet portion 541m. S1 can be included. At this time, since the rotational force application part 550 having magnetism is provided at one end of the cylindrical cam 541, the first sensor S1 is provided with the first magnet by providing the first magnet part 541m at the other end of the cylindrical cam 541. It is preferable that the position or movement of the portion 541m can be detected more precisely. On the other hand, in the drawing, the first magnet portion 541m is illustrated as being provided on the cylindrical cam 541, but the first sensor S1 may be provided on the cylindrical cam 541. However, when the signal output from the first sensor S1 is transmitted to the control unit 440, the housing 512 or the first frame 522 is fixed as compared with the case where the first sensor S1 is provided in the rotating cylindrical cam 541. It is advantageous to simplify the structure and improve the manufacturing efficiency that the first sensor S1 is provided in the structure.

  As a result, the degree of rotation of the cylindrical cam 541 can be accurately measured, and as a result, the position of the ultrasonic wave generation unit can be determined.

  The ultrasonic generation device 20 according to the other embodiment may include a second magnet unit 531m provided in the ultrasonic generation unit and a second sensor S2 disposed to face the second magnet unit 531m. Here, in FIG. 9 and the like, the configuration in which the second magnet portion 531m is provided in the transfer member 531 is illustrated, but the second magnet portion 531m may be provided in the transducer 514. In the drawing, the second magnet portion 531m is illustrated as being provided on the transfer member 531, but the second sensor S2 may be provided on the transfer member 531. However, when the signal output from the second sensor S2 is transmitted to the control unit 440, the housing 512, the second frame 525, or the like is fixed as compared with the case where the second sensor S2 is provided in the linearly moving transfer member 531. It is advantageous to simplify the structure and improve the manufacturing efficiency if the second sensor S2 is provided in the structure.

  On the other hand, the second sensor S2 is provided at a position facing the second magnet portion 531m. As described above, since the transfer member 531 and the transducer 514 reciprocate linearly inside the first cartridge 510, the movement range is limited. That is, the transfer member 531 performs a linear reciprocating motion only in a region between the position where the transfer member 531 is farthest from the rotational force application unit 550 and the position where the transfer member 531 is closest to the rotational force application unit 550. That's right. Here, a position where the transfer member 531 is farthest from the rotational force application unit 550 may be a first reference point, and a position where the transfer member 531 is closest to the rotational force application unit 550 may be a second reference point. it can. In this case, when the transfer member 531 is positioned at the first reference point, the second sensor S2 can be disposed at a position where the transfer member 531 is closest to the second magnet portion 531m. Further, the second sensor S2 may be disposed at a position where the transfer member 531 is closest to the second magnet portion 531m when the transfer member 531 is positioned at the second reference point. As a result, the position sensing means can accurately detect the position of the ultrasonic generator even at a turning point where the direction of motion of the ultrasonic generator is changed. Further, this makes it possible to accurately detect the moment when the linear motion of the ultrasonic wave generator starts one cycle and the cycle ends. That is, it is possible to accurately detect the initial position of the ultrasonic generator and the movement end position of the ultrasonic generator.

  In a system in which the rotational force is transmitted in a state where the rotational force applying unit 550 and the outer rotating unit 453 are coupled by magnetic force instead of being coupled by direct contact, the rotational movement and rotation of the outer rotating unit 453 are performed. There may be a case where the rotational motion of the force application unit 550 does not perfectly match. At this time, the position of the ultrasonic generator is precisely measured or the degree of movement of the ultrasonic generator is completely controlled simply by controlling or measuring the degree of rotation of the outer rotating unit 453. Sometimes it is not possible. Therefore, if there is no separate means capable of accurately grasping the position of the ultrasonic wave generation unit, as described above, there is a risk that the ultrasonic wave is excessively applied to the specific position to induce various problems.

  However, the ultrasonic generation apparatus 20 according to the other embodiment described above includes the position sensing unit and the control unit described above, thereby accurately grasping the position of the ultrasonic generation unit and reflecting it in the ultrasonic generation operation control. Therefore, the risk described above can be significantly reduced.

  On the other hand, a separate frame or the like is provided inside the housing 512, and the first sensor S1, the second sensor S2, and the like can be fixed at appropriate positions by this frame. For example, the first sensor S1 can be fixed to the first frame 522 provided in front of the cylindrical cam 541, and the second sensor S2 is fixed to the second frame 525 provided near the cylindrical cam 541. Can do. Here, the shaft protrusion 542 of the cylindrical cam 541 can also be inserted into the first frame 522 and fixed rotatably. Also, a plurality of first sensors S1 and first magnet portions 541m can be provided so that the rotation of the cylindrical cam 541 can be detected more precisely. In addition, the first terminal 512T1 connected to the first sensor S1 and the second terminal 512T2 connected to the second sensor S2 are configured to be exposed to the outside of the housing 512, so that the treatment handpiece 410 is provided. The signals output from the first sensor S1 and the second sensor S2 can be transmitted to the control unit 440 by contacting the first contact 410T1 and the second contact 410T2 respectively. Here, the controller 440 may be connected to the motor 450 to control the rotation of the motor 450. The motor 450 is fixed inside the treatment handpiece 410 through the third frame 415.

  In the other embodiment, a transmission member can be provided in the first cartridge 510 in a direction through which the ultrasonic wave generated by the transducer 514 passes. At this time, the transmission member can be configured by a first window 512w made of a material that can smoothly transmit ultrasonic waves.

  In the other embodiment, a protective cap 570 coupled to the outside of the first cartridge 510 may be provided. Here, a second window 571 made of a material capable of smoothly transmitting ultrasonic waves can be provided in the direction in which the ultrasonic waves pass through the protective cap 570.

  The protective cap 570 has a function of preventing damage or contamination of the first window 512w described above. That is, if the first window 512w is damaged, the first cartridge 510 must be repaired or discarded, but if the second window 571 of the protective cap 570 is damaged, only the protective cap 570 is replaced. Thus, the first cartridge 510 can be used continuously. Therefore, the life of the cartridge can be extended.

  In addition, by changing the thickness of the protective cap 570, it is possible to adjust the ultrasonic irradiation depth. That is, compared with the case where the thin protective cap 570 is used, when the thick protective cap 570 is used, the depth at which the thermal lesion occurs can be made close to the skin surface.

  The empty space inside the first cartridge 510 is filled with fluid (L). The fluid (L) serves as a kind of medium for smoothly transmitting the ultrasonic wave generated by the transducer 514 to the outside of the first cartridge 510. The fluid (L) can also have a function of cooling the transducer 514. For example, a heat generation phenomenon may be induced in the process of generating ultrasonic waves by the transducer 514. Such a heat generation phenomenon can be mitigated by the fluid (L) described above.

  Therefore, at least the region from the transmission member of the first cartridge 510 to the transducer 514 needs to be filled with the fluid (L) described above. In addition, while the first cartridge 510 is coupled to the treatment hand piece 410 and the first cartridge 510 is in contact with the body of the treatment subject and the treatment is being performed, the transmission member of the first cartridge 510 is always vertical. It may not be pointing down. Therefore, it is preferable to determine the filling amount of the fluid (L) described above in consideration of the inclination range in the direction in which the transducer 514 is directed during the treatment. Of course, it is also possible to fill the empty space inside the first cartridge 510 with the above-described fluid (L).

  On the other hand, when the fluid (L) is filled in the first cartridge 510 as described above, the flow-off cycle of the fluid (L) may change depending on the degree of sealing inside the first cartridge 510. For example, when the sealing degree is low, the fluid (L) inside the first cartridge 510 decreases as time elapses. In this case, there may be a problem that the fluid (L) must be replenished or the first cartridge 510 itself must be replaced. However, in the ultrasonic generator 20 according to the other embodiment, the rotational force application unit 550 provided inside the cartridge receives the rotational force provided from the outer rotation unit 453 provided outside the cartridge, and is applied thereto. The transducer 514 can be linearly moved or linearly reciprocated by converting the obtained rotational force through the converter. Further, since the rotational force application unit 550 and the outer rotation unit 453 are coupled by magnetic force, the sealing degree of the first cartridge 510 can be improved. That is, the ultrasonic generator 20 according to the other embodiment uses the driving force external to the first cartridge 510 even if there is no component penetrating the outer wall of the first cartridge 510 or the housing 512. Deducer 514 can be linearly moved or linearly reciprocated.

  Therefore, the ultrasonic generator 20 according to the other embodiment improves the sealing degree of the cartridge as compared with a case where a component that moves the transducer 514 through the outer wall of the cartridge or the housing 512 is necessary. As a result, the cartridge replacement cycle can be extended to improve the convenience of use and maintenance of the ultrasonic generator 20. In addition, the ultrasonic generator 20 according to the other embodiment does not need to be provided with a separate unit for improving the sealing degree of the cartridge, but is simplified through the above-described rotational force applying unit 550 and the conversion unit. With this structure, the transducer 514 can be linearly moved or reciprocated linearly, which is advantageous in reducing the size of the cartridge and the treatment handpiece 410 and reducing the manufacturing cost.

  Although the first cartridge 510 has been described above as a reference, the second cartridge 510-1 and the third cartridge 510-2 can be configured in a similar manner to the first cartridge 510, and redundant description is omitted.

  Moreover, S3 displayed in FIG. 6 means a third sensor, and an embodiment including the third sensor and the like will be described later with reference to FIGS.

  Hereinafter, still another embodiment of the present invention will be described with reference to FIGS. Here, the description which overlaps with the content described above is omitted.

  As described above, the cartridge can be configured to be detachable from the surgical handpiece 210. For example, a guide portion 214 for fastening with the first cartridge 310 is provided at the front end of the handle portion 212. In still another embodiment, the guide part 214 may have a bar shape protruding in the shearing direction of the handle part 212. A through hole 312 a having a shape corresponding to the cross-sectional shape of the guide portion 214 is formed in the central region of the cartridge main body 312 of the first cartridge 310. As shown in FIG. 12, the first cartridge 310 is mounted on the surgical handpiece 210 by inserting the guide portion 214 into the through hole 312a. At this time, in order to prevent the mounting state of the first cartridge 310 from being released, a locking device 214a is provided at the front end of the guide portion 214, and the practitioner rotates the locking device 214a. The first cartridge 310 can be locked or unlocked.

  An image probe 216 for visualizing the tissue to be treated is provided inside the guide portion 214. The image probe 216 may have a substantially bar shape along the guide portion 214. The image probe 216 can generate image ultrasound so that the skin tissue to be treated, that is, the subcutaneous fat layer can be imaged. The guide portion 214 is configured to be positioned above the transducer 314 provided in the first cartridge 310 when the first cartridge 310 is fastened to the treatment handpiece 210. Accordingly, the transducer 314 irradiates the HIFU while moving back and forth in the lower part of the guide portion 214, and the image probe 216 is commonly used for the cartridge and generates a separate image ultrasonic wave to generate subcutaneous fat. The layer can be visualized and displayed on the display unit 110.

  Here, a driver 218 may be provided on the treatment handpiece 210 for the back-and-forth movement of the transducer 314. In still another embodiment, the driver 218 includes a stepping motor and a rotating motor, and a gear, a belt, and a pulley operated by such a motor ( pulley) and the like, and the driver 218 and the transducer 314 are connected by a support 316. As a result, the driver 218 moves the support 316 back and forth, tilting and up and down, so that the transducer 314 is moved back and forth, tilting and up and down. In this way, the driver 218 is provided to be used in common with the cartridge, and can move the respective transducer module 314 of the cartridge back and forth.

  The driver 218 can move the transducer 314 in the front-rear direction so that the transducer 314 has a treatment section of approximately 40.0 mm to 100.0 mm. More specifically, the driver 218 is composed of a stepping motor, and the transducer 314 is moved back and forth by a length selected within a range of approximately 40.0 mm to 100.0 mm. can do. At this time, the transducer 314 can irradiate the HIFU while moving in the range. The transducer 314 is set to irradiate the HIFU at a certain interval such that the thermal lesion 20 forms a plurality of dots along the same line, or the thermal lesion It may be set to irradiate HIFU so that 20 forms a straight line without an interval.

  When the transducer 314 moves back and forth below 40.0 mm, the treatment time for the skin lifting, skin tightening, or subcutaneous fat layer is small, and therefore the treatment time may be very long. The transducer module 314 is set to irradiate HIFU at a certain depth, and the subcutaneous fat layer is bent and spreads in both directions with reference to the human navel, so the transducer 314 In the case where the range of back-and-forth movement exceeds 100.0 mm, the initial HIFU irradiation depth and the final HIFU irradiation depth for the subcutaneous fat layer are different, and there is a risk that HIFU will be irradiated to a region outside the subcutaneous fat layer. May be very expensive. Such a risk can occur similarly in skin lifting or skin tightening. Therefore, the driver 218 is set so that the transducer 314 can move back and forth within a range of approximately 40.0 mm to 100.0 mm, more preferably within a range of 60.0 mm to 80.0 mm. This is advantageous for shortening the treatment time while ensuring the treatment safety. However, when the transducer 314 is used for cancer or tumor treatment, the range of movement of the transducer 314 in the back-and-forth direction can be changed to suit the size or form of the cancer or tumor treatment. That is, if the size of the cancer or tumor is less than 40.0 mm, it is preferable that the range of movement of the transducer 314 in the front-rear direction is adjusted to less than 40.0 mm so as to match this.

  The first cartridge 310 may be provided with a cooling fluid for cooling the heat generated by the operation of the transducer 314. In the still other embodiment, the first cartridge 310 is configured to be filled with cooling water, and the cooling water is circulated by a separate cooling water circulation line (not shown), thereby The overheating phenomenon of the transducer 314 can be prevented. Therefore, when the first cartridge 310 is mounted on the treatment handpiece 210, the cooling water in the first cartridge 310 is connected to the cooling water circulation line, and the cooling water circulation line is connected to the interior of the equipment body 100. The cooling water storage container (not shown) is connected to the cooling water storage container, and the cooling water in the cooling water storage container can be circulated. On the other hand, although not shown, circulating means such as a pump is installed on the cooling water circulation line.

  The ultrasonic generator 10 having the above-described structure can selectively attach the cartridge having conditions suitable for different types of treatments to the treatment handpiece 210. A cartridge capable of performing treatment can be selected, and the cartridge can be attached to the treatment handpiece 210 for treatment. This makes it possible to perform a variety of procedures simply by exchanging cartridges with a single device. Compared to high-intensity focused ultrasound medical devices that can perform only single-purpose treatments, the structure of a multi-purpose ultrasound medical device Can be realized.

  In particular, in the case of non-invasive ultrasonic treatment of face lifting, non-invasive ultrasonic treatment of subcutaneous fat layer reduction, and cancer and tumor removal treatment, the depth and intensity conditions of high-intensity focused ultrasound, and the skin to be imaged Since the tissues are completely different, it is very difficult to perform at least two of these procedures with one piece of equipment. However, the ultrasonic generator 10 according to the still another embodiment, after forming the driver 218 or the image probe 216 or the like shared for the cartridges having different treatment purposes in the treatment handpiece 210, This technical barrier can be eliminated by enabling different procedures through cartridge replacement.

  As described above, the ultrasonic generator 10 according to the still another embodiment includes the cartridge set 300 composed of cartridges having different treatment purposes, and then selects a cartridge that can perform a desired treatment. By attaching to the treatment handpiece 210, a desired treatment can be performed for each treatment purpose. As a result, the ultrasonic generator 10 according to the present invention is a treatment handpiece 210 for a cartridge for a desired treatment purpose among face lifting, skin tightening treatment, subcutaneous fat layer reduction or removal treatment, and tumor or cancer removal treatment. Two or more high-intensity focused ultrasonic treatments can be performed with a single device by attaching to the device.

  Next, with reference to FIGS. 13 to 20, a case where the still another embodiment includes the sensing means SM and the like will be described.

  Referring to FIGS. 13 to 20, the ultrasonic generator 10 according to still another embodiment includes a sensing unit SM. Furthermore, the control unit 150 and the speaker 160 may be included.

  In the still other embodiment, the sensing means SM has a function of sensing at least one of the amount of fluid (L) and the tilt of the cartridge. Then, a warning signal can be output using the result sensed by the sensing means SM, or the operation of the transducer 314 can be interrupted.

  Specifically, the sensing means SM may include a third sensor S3 that senses the amount of fluid (L). The sensing means SM may include a fourth sensor S4 that detects at least one of tilt, acceleration, and angular velocity.

  In addition, the ultrasonic generator 10 according to the still other embodiment uses the result sensed by the sensing means SM to determine whether the fluid (L) is insufficient, and whether the cartridge tilt deviates from the normal range. The control unit 150 may be included. In addition, when an abnormal state occurs, an output means for outputting a warning signal can be included in order to make a user such as a practitioner recognize this. At this time, the output means can output a visual warning signal or an audible warning signal, and the visual warning signal can be output through the display 110 described above. A speaker 160 or the like is used for output.

  In addition, the ultrasonic generator 10 according to still another embodiment improves safety by stopping the operation of the transducer 314 and blocking the generation of ultrasonic waves when the inclination deviates from a predetermined normal range. Can be made.

  In yet another embodiment, the third sensor S3 is a sensor that senses the presence or absence of contact with the fluid (L). That is, if the state in which the third sensor S3 is immersed in the fluid (L) is a normal state, the state in which the third sensor S3 is exposed to the outside of the fluid (L) becomes an abnormal state, and the third sensor S3 A signal value different from the signal value output in the normal state can be output in the abnormal state. For example, in the normal state, the third sensor S3 may not output a signal or output a Low value, and in the abnormal state, a predetermined signal value such as a High signal may be output.

  The fluid (L) is the cooling fluid described above. That is, the fluid (L) can have a function of preventing a phenomenon in which the transducer 314 and adjacent components are overheated by heat generated in the process of generating ultrasonic waves. The fluid (L) can also serve as a medium that allows the ultrasonic waves generated by the transducer 314 to be smoothly transmitted to the outside of the first cartridge 310.

  In yet another embodiment, a transmitting member 318 is provided in the first cartridge 310 in the direction through which the ultrasonic waves generated by the transducer 314 pass. At this time, the transmission member 318 can be formed of a window made of a material such as a film that can smoothly transmit ultrasonic waves.

  Therefore, at least the region from the transmission member 318 to the transducer 314 of the first cartridge 310 needs to be filled with the fluid (L) described above. Further, the transmission member 318 of the first cartridge 310 is not always directed vertically downward while the first cartridge 310 is coupled to the treatment handpiece 210 and is in contact with the body of the treatment subject. There is also. Therefore, it is preferable to determine the filling amount of the fluid (L) described above in consideration of the inclination range in the direction in which the transducer 314 is directed during the treatment. Of course, it is also possible to fill the empty space inside the first cartridge 310 with the above-described fluid (L).

  Hereinafter, the case where the empty space inside the first cartridge 310 is filled with the fluid (L) will be described as a reference. However, as described above, the reference water level of the fluid (L) is set in the first cartridge 310 even when the fluid (L) is set not to fill the empty space in the first cartridge 310. Preferably, the reference water level can be seen on the inner upper surface of the first cartridge 310 or the inner lower surface of the first cartridge 310 described later.

  Here, when the sealing degree of the first cartridge 310 is low, the fluid (L) filled in the first cartridge 310 is reduced. In addition, as described above, when the fluid (L) has a cooling function, the amount of the fluid (L) is further reduced by being evaporated or naturally evaporated in the cooling process. By the way, when the decrease of the fluid (L) is continued and the amount of the fluid (L) decreases below a predetermined reference amount required, the transmission rate of the ultrasonic wave decreases, the transducer 314 or the like There is a risk of overheating.

  In order to prevent such a problem, the ultrasonic generator 10 according to another embodiment described above uses the third sensor S3 described above to supply the fluid (L) filled in the first cartridge 310. Sense the amount. For example, as shown in FIG. 14, when the third sensor S3 is located on the inner upper surface of the first cartridge 310, the amount of the fluid (L) decreases and the third sensor S3 becomes the fluid (L). A predetermined signal value such as an H signal is transmitted to the control unit 150 when an abnormal state that is not soaked occurs. The control unit 150 determines an abnormal state based on the signal value provided from the third sensor S3, and outputs a fluid (L) shortage state through the display 110, or outputs a warning sound through the speaker 160. be able to. As a result, a user using the ultrasonic generator 10 according to the other embodiment, such as a practitioner, can quickly recognize that the fluid (L) in the first cartridge 310 is insufficient. It is possible to take appropriate measures such as filling the fluid (L) and replacing the cartridge.

  In the still other embodiment, a plurality of third sensors S3 may be provided on the inner upper surface of the first cartridge 310 so as to be separated from each other. Referring to FIG. 15, the IV-IV ′ line cross section of the first cartridge 310 may have various shapes, and the third sensor S3 may be disposed at various positions depending on the shape of the first cartridge 310. Will understand.

  Referring to FIG. 16, as the first cartridge 310 is tilted, some of the third sensors S3 can output an abnormal signal, and the other third sensors S3 can output a normal signal. You can understand. As described above, by disposing the third sensor S3 at a predetermined interval on the inner upper surface of the first cartridge 310, the inclination of the first cartridge 310 can be detected without a separate inclination sensor.

  In another embodiment different from the above-described other embodiments, the sensing means SM has a vertical line (or upper surface) perpendicular to the fluid (L) water surface (or top surface) and an imaginary straight line connecting the center of the transmission member 318 and the center of the transducer 314 It is possible to detect whether or not the image is horizontal. That is, the sensing means SM can sense the inclination or flatness of the fluid (L) water surface. At this time, the third sensor S3 can be formed of an optical sensor. For example, the sensing unit SM may include one in which a light emitting unit is provided in one third sensor S3 and a light receiving unit is provided in the other third sensor S3 among the plurality of third sensors S3. Here, the light output from the third sensor S3 can employ various wavelengths such as infrared rays. Then, the third sensor S3 provided with the light emitting unit and the third sensor S3 provided with the light receiving unit are arranged so as to be spaced apart from each other. Accordingly, only one of the third sensor S3 provided with the light emitting part and the third sensor S3 provided with the light receiving part is immersed in the fluid (L), and the other one is exposed to the outside of the fluid (L). In the state, the light is refracted at the fluid (L) water surface (the boundary surface between the fluid and the gas), so that the light output from the light emitting unit cannot reach the light receiving unit. On the other hand, the third sensor S3 provided with the light emitting part and the third sensor S3 provided with the light receiving part are all exposed to the outside of the fluid (L), or all of them are immersed in the fluid (L). In the state where the light is emitted, the light output from the light emitting unit reaches the light receiving unit. Therefore, it is possible to detect whether or not the first cartridge 310 is within the reference inclination range by arranging the third sensor S3 in consideration of the fluid (L) water surface due to the reference inclination range of the first cartridge 310. it can. The case where the light emitting unit and the light receiving unit are provided at separate positions has been described above, but the light output from the light emitting unit is also provided when the light emitting unit and the light receiving unit are provided at the same position. It will be understood that a principle similar to that described above can be realized by configuring so that is reflected on the inner wall surface of the first cartridge 310 and applied to the light receiving unit.

  In the still other embodiment, the third sensor S3 is disposed on the outer periphery of the upper inner surface of the first cartridge 310 as shown in FIG. Accordingly, since the change in the height of the third sensor S3 with respect to the change in the tilt of the first cartridge 310 is increased, the tilt of the first cartridge 310 can be detected more precisely.

  If the first cartridge 310 is tilted excessively, there is a risk that ultrasonic waves are applied to unintended positions. At this time, there is a possibility that damage is induced in the treatment subject or the body of the practitioner. In particular, if the transducer 314 generates high intensity focused ultrasound to form the thermal lesion 12 in place, the risk may be further increased.

  In order to solve such a problem, the ultrasonic generator 10 according to another embodiment described above blocks the generation of ultrasonic waves when the inclination of the first cartridge 310 deviates from a predetermined range. .

  That is, as described above, when the tilt of the first cartridge 310 is sensed and the tilt of the first cartridge 310 deviates from the normal range, the control unit 150 shuts off the power supply provided to the transducer 314. Alternatively, the ultrasonic generation operation of the transducer 314 can be interrupted. As a result, it is possible to reduce a risk that occurs when the first cartridge 310 is excessively inclined.

  In particular, if an ultrasonic wave is generated with the transmission member 318 of the first cartridge 310 facing upward, the ultrasonic wave may be transmitted to a practitioner or a surgical assistant, leading to a dangerous situation. Further, when the amount of the fluid (L) filled in the first cartridge 310 is not sufficient, the transmission member 318 may be damaged when the ultrasonic waves are emitted upward in this way. As a result, the leakage of the fluid (L) deepens, the first cartridge 310 malfunctions, and the safety and reliability are greatly reduced.

  Here, referring to FIGS. 17 and 18, the third sensor S <b> 3 may be disposed in a region between the transmission member 318 and the transducer 314 of the first cartridge 310 in the still other embodiment. In this case, when the transmission member 318 of the first cartridge 310 faces downward, the third sensor S3 cannot measure the amount of the fluid (L) or measure the inclination of the first cartridge 310. . However, when the transmission member 318 of the first cartridge 310 is directed upward, the third sensor S3 can measure the amount of the fluid (L). That is, when the third sensor S3 is not immersed in the fluid (L), it can be determined that the amount of the fluid (L) is insufficient.

  In addition, as described above with reference to FIGS. 14 to 16, in the still other embodiment, the third sensor S <b> 3 can be disposed near the lower surface inside the first cartridge 310. In addition, by disposing the plurality of third sensors S3 at a predetermined interval, the inclination of the first cartridge 310 can be detected based on the same principle as described above. Therefore, the ultrasonic generator 10 according to the other embodiment described above can detect the degree to which the transmission member 318 of the first cartridge 310 is tilted to one side with reference to the vertical upper side in the state in which the transmission member 318 faces upward. At this time, when the transmission member 318 of the first cartridge 310 is tilted to one side within a predetermined angle with respect to the vertical upper side in the state of facing upward, a dangerous situation may occur as described above.

  Therefore, when the transmission member 318 of the first cartridge 310 is in an upward direction as a reference, the ultrasonic wave generation of the transducer 314 is interrupted when it is within an inclination range of 10 degrees or less on one side. It is preferable.

  Further, referring to FIG. 19 and FIG. 20, the sensing means SM of the ultrasonic generator 10 according to still another embodiment may include a fourth sensor S4. Here, the fourth sensor S4 is a sensor that detects at least one of tilt, angular velocity, and acceleration.

  Here, the fourth sensor S4 can be configured by a normal inclination sensor, an acceleration sensor such as an inertial or gyroscopic silicon semiconductor sensor, an angular velocity sensor, or the like. Since the principle and method of such a sensor are already widely known, a specific description is omitted in this specification.

  On the other hand, the fourth sensor S4 is provided in the treatment handpiece 210 as shown in FIG. 9, or is provided in the cartridge as shown in FIG. Here, when the fourth sensor S4 is provided in the surgical handpiece 210, the fourth sensor S4 provided in the surgical handpiece 210 is jointly used without providing the fourth sensor S4 in each of the described cartridge sets. be able to. Then, the fourth sensor S4 is connected to the control unit 150, and the control unit 150 receives a signal generated by the fourth sensor S4, whereby the tilt of the cartridge is monitored.

  As another example, a relay that can be turned on or off between the transducer 314 and a power supply line (not shown) is connected to the fourth sensor S4 so that it can be quickly changed based on the tilt of the cartridge. The ultrasonic generation operation can be interrupted or executed. Therefore, compared with the case where the transducer 314 is controlled via the control unit 150 configured as software on separate hardware such as an equipment main body, the interruption or execution of ultrasonic generation is more quickly adjusted with a simple configuration. can do.

  Referring to FIG. 21A, it can be said that the first cartridge 310 according to the above embodiment of the present invention is used for a treatment for reducing a relatively thick subcutaneous fat layer. In the still another embodiment, the first cartridge 310 is used when the thickness (T1) of the subcutaneous fat layer 20 to be treated is 25.0 mm or more. That is, the first cartridge 310 is set under the condition that it cannot be performed unless the thickness (T1) of the subcutaneous fat layer 20 is 25.0 mm or more. In this case, the treated patient is likely to be a highly obese patient. In the first cartridge 310, the vertical length (H1) of the HIFU lesion 30 is adjusted to approximately 8.0 to 12.0 mm, and the irradiation depth of the HIFU from the skin surface is approximately 11.0 to 15 mm. Adjusted to 0.0 mm. When the vertical length (H1) of the HIFU lesion 30 is less than about 8.0 mm, the reduction efficiency of the subcutaneous fat layer 20 may be reduced. On the other hand, when the vertical length (H1) of the HIFU lesion 30 exceeds approximately 12.0 mm, a HIFU lesion may be formed in a region outside the subcutaneous fat layer 20. If the irradiation depth is less than about 11.0 mm or exceeds about 15.0 mm, the HIFU lesion 30 may be detached from the subcutaneous fat layer 20 at the time of surgery. Therefore, in the transducer 314 of the first cartridge 310, the vertical length (H1) of the HIFU lesion 30 is adjusted to approximately 10.0 mm ± 2.0 mm, and the irradiation depth of the HIFU is 13.0 mm ± When the thickness is adjusted to 2.0 mm, there is a risk that the skin tissue other than the subcutaneous fat layer 20 is treated even if the thickness (T1) of the subcutaneous fat layer 20 is 25.0 mm or more. Can be relaxed.

  Here, the transducer 314 of the first cartridge 310 may be configured to generate a plurality of the HIFU lesions 30 while performing a forward movement or a backward movement, that is, a linear reciprocation. At this time, the interval between the HIFU lesions 30 does not have the interval or is less than 1.0 mm so that the HIFU lesion 30 has a shape of a straight line or a column that is not interrupted in the middle. However, the subcutaneous fat layer 20 can be thermally decomposed. However, if the HIFU lesions 30 overlap with each other, the pain felt by the patient may increase, so it is ideal that HIFU is irradiated as close as possible under the condition that the HIFU lesions 30 do not overlap. .

  Referring to FIG. 21B, the second cartridge 310-1 according to the embodiment of the present invention is used for a treatment for reducing a relatively thin subcutaneous fat layer compared to the first cartridge 310 described above. It can be said that. In the still other embodiment, the second cartridge 310-1 is used when the thickness (T2) of the subcutaneous fat layer 40 to be treated is 7.0 mm or more and less than 25.0 mm. That is, the second cartridge 310-1 is set under conditions that allow the operation when the thickness (T2) of the subcutaneous fat layer 40 is at least 7.0 mm and is thinner than 25.0 mm. I can say that. In this case, the treated patient is likely to be a highly obese patient. In the second cartridge 310-1, the vertical length (H2) of the HIFU lesion 50 is adjusted to approximately 5.0 mm to 9.0 mm, and the irradiation depth of the HIFU from the skin surface is approximately 6.0 mm to It is adjusted to 10.0 mm. When the vertical length (H2) of the HIFU lesion 50 is less than about 5.0 mm, the reduction efficiency of the subcutaneous fat layer 20 may be reduced. On the other hand, when the vertical length (H2) of the HIFU lesion 50 exceeds approximately 9.0 mm, a HIFU lesion may be formed in a region outside the subcutaneous fat layer 40. Further, if the irradiation depth is less than about 6.0 mm or exceeds about 10.0 mm, the HIFU lesion 50 may be detached from the subcutaneous fat layer 40 at the time of surgery. Therefore, in the transducer 314 of the second cartridge 310-1, the vertical length (H2) of the HIFU lesion 30 is adjusted to approximately 7.0 mm ± 2.0 mm, and the irradiation depth of the HIFU is 8. When the thickness is adjusted to 0 mm ± 2.0 mm, the skin tissue other than the subcutaneous fat layer 40 is treated even when the thickness (T2) of the subcutaneous fat layer 20 is 7.0 mm or more and less than 25.0 mm. Risk can be mitigated.

  Here, the transducer 314 of the second cartridge 310-1 may be configured such that a plurality of the HIFU lesions 50 are generated while performing forward movement or backward movement, that is, linear reciprocation. At this time, the interval between the HIFU lesions 50 is such that there is no interval or less than 1.0 mm so that the HIFU lesion 50 has a shape of a straight line or a column without interruption in the middle. The subcutaneous fat layer 40 can be thermally decomposed. However, if the HIFU lesions 50 overlap with each other, the pain felt by the patient may increase. Therefore, it is ideal that HIFU is irradiated as close as possible under the condition that the HIFU lesions 50 do not overlap. is there.

  The ultrasonic generator according to the present invention and a treatment method using the same are useful as devices that can be used for various treatments such as obesity treatment, skin beauty, and gynecological disease treatment.
